Description

ABSTRACT:
A NAND flash memory device, and methods of forming and operating the same are provided. The NAND flash memory device includes first and second selection gate lines sequentially disposed at one side of a plurality of cell gate lines. A first selection transistor including the first selection gate line serves as a buffer for decreasing a highly boosted channel voltage of a non-selected cell to minimize the leakage current of the NAND flash memory device.
